Solar Cell Efficiency Rises By 30% Through Singlet Fission

Scientists were pretty excited when they discovered you could convert light energy directly into electricity by capturing photons in semiconductors, exciting them into “excitons” (bound electron with negative charge and hole with positive), and capturing the resultant current through electrodes. … Continue reading

MIT device uses heat store to crank up solar panel output

US researchers have found a way to use heat to improve the efficiency of solar panels. Photovoltaic (PV) cells typically produce less electricity the hotter they get, but the engineers from Massachusetts Institute of Technology (MIT) have developed a solar-powered … Continue reading
